IMPROVEMENT IN SUGAR-MILLS.

Speeilieation forming part of Letters Patent No. 41,265, dated January12, 1364; antcdatcd December 10, 1863.

To all whom; it may concern:

Be it known that I, LUTHER E. PORTER, of Lake Mills, in the county ofJefferson and State of Wisconsin, have invented certain new and usefulImprovements in Sugar-Mills; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and the letters and iigures marked thereon,which form part of this specification.

In said drawings, Figure l represents aside View of my invention. Figs.2 and 3 are rcspectively a longitudinal and cross section of the'sliding fulcrum G. Fig. Lt is afront and top view of the loop c, andFig. 5 is a view of the lower side of the lever E.

Similar letters in the diiierent figures indicate corresponding parts ofmy invent-ion.

The nature of my invention consists in a novel inode of adjusting thecrushing-rollers of a sugar-mill by means of a lever operating uponsliding journal-boxes sul'lporting the rollers, so that the pressure ofsaid rollers upon the cane is equal throughout the entire length ofthecane, notwithstanding the const-ant variation in the size thereof.

To enable others skilled in the art to understand how to construct anduse my invention, I will proceed to describe the same withpariicularity, reference being made to the drawings. l

InA Fig. l, I-I II represent the end frame, which supports thecrushing-rollers, of which there are three, arranged horizontally in thepositions i ndicated by the dotted circles marked A B O. The position ofthe rollers B O between which 'the cane is fed oigput into the mill, isiixed; but the journals of the-roller marked A a av are supported in asliding box, (marked D,) which istted in a groove in the end frames,running toward thevcenter of the roller C, so that the said roller A canmovetoward or recede from the roller C, as may be desired. The saidrollerA is'kept in position by means of the lever E, operating upon theadjustable journal-box D, as shown, resting upon the fulcrum G, which 1sadjustable longr tudinally upon the shoulder H by means of the screw sand the nut a, or in any other suit'- able manner.

d represents a small ball, which serves as a bearing between the leverE-.and the sliding box D, and Amaybe adjusted at diiferent polnts nPQilsaid lever, so that, 1n connection with the sliding fulcrum Ur, theshort'arm of said lever may be varied in length., as may be desired. Aweight, IV, is attached to the long arm of the lever E, of such weightand at such point thereupon as to cause the proper amount of pressureupon the sliding box l); or an ach ditional lever, F. may be employed incombination with the lever E, as shown; or, if a still greater pressureshould be desirable, the lever F may be arranged as shown by the dottedlines, by employing a loop, Fig. 4, of sufeient length. In the drawingsthearrange'mcnt is shown only at one end of the roller A; but the samedevice, arranged in the same manner, is employed at each end of theroller, and, being duplicates, only one view is shown.

The operation of my invention is as follows: The weights W beingsuspended upon the levers E, the roller A is pressed up against theroller C. The cane is put into the mill between the rollers B G, asindicated bythe red arrows, which are at such a distance apart as tobreak and partially crush the cane, which passes along and entersbetween the rollers A O, which press closely upon the cane and extractthe juice, the pressure being equal throughout the entire length andvaried diameter of the cane by means of the operation ot the le'ver and'weight, as described. Instead of operating said lever by means of aweight, as shown, a spring or other mechanical device maybe employed,though I deem the employment of weights the cheapest and simplestmethod.

I do'not confine myself to the particular arrangement oi the leversshown and described, the material point being that the -sliling boxshall be adjusted by a lever provided with a suitable fulcrum, andoperated by any power properly applied.

Vhat I vdo claim as my invention, and desire to seeurelby LettersPatent, is-

1. The combination and arrangement of the roller A, the adjustablejournal-box D, with a lever or combination of levers, operatingsubstantiall y as and for the purposes herein specied and shown.

2. In combination with said adjustable box and levers, the employment ofthe sliding fulcrunn G, arranged and operating as and for the purposesherein shown and described.
